SCHUL 72 Attorney BACKGROUND OF THE INVENTION Heretofore, a longitudinal member, such as a wire, rod, or the like, has been wound into a wound coil or bundle on a winding apparatus of the type shown in US. Pat. No. 2,655,323, issued Oct. 13, 1953, to Wiggan and assigned to the same assignee as the present application. The coil winding apparatus comprises a generally rotatable horizontal shaft on which a continuously rotating takeup block is mounted. After attaching a free end of the longitudinal wire, rod, or the like to the continuously rotating takeup block, the longitudinal member is wound into a wound coil or bundle on the rotating takeup block. After a predetermined mount of wire has been wound, such as about 200 to 2,000 pounds of wire, the operator cuts one of the last wound turns of the coil to form a wound coil or bundle of predetermined weight. Previously, the wound coil was stripped by the operator onto a free swinging hoist hook, which hook was unstable to control and unsafe for the operator.

Later, as shown in the above-mentioned U.S. Pat. No. 2,655,323, the takeup block was provided with a swivelable eye and a chain (having a snap hook at one end) was connected to the centrally mounted eye. The other end of the chain was attached, by means of a ring, to the hoist hook. In operation, the operator would remove the would coil from the rotating takeup block with the chain passing through the wound coil and deposit the wound coil on the floor adjacent the rotating winding machine. The snap hook was then unfastened from the eye and connected to the ring adjacent the frame hoist hook, whereupon the wound coil was raised by the hoist and transported to another location.

OBJECTS OF THE INVENTION It is the general object of this invention to avoid and overcome the foregoing and other difficulties of and objections to prior art practices by the provision of an improved method of and apparatus for receiving a wound coil from a coil winding machine, which method and apparatus:

a. eliminate the step of depositing the wound coil on the floor adjacent the coil winding machine preparatory for the transfer operation;

b. eliminate the use of the eye, snap hook, chain, and ring employed in conventional transfer devices;

c. position the hoist hook in a stable position where it is easy to control during the transfer operation;

(I. eliminate the operator hazards formerly associated with the conventional transfer devices;

e. provide apparatus which is simple and rugged in construction;

f. handle a wide range ofweights of wound coils; and

g. completely eliminate danger of injury to the operator of the coil winding machine during the transfer operation.
